Kidde WK-890181-000 Electric Control Head

Overview

The Kidde WK-890181-000 is a 24 VDC electric control head designed to actuate the cylinder valve on Kidde CO2 and clean agent fire suppression system storage cylinders. When the facility fire alarm control panel or dedicated releasing panel sends a discharge signal, the control head’s internal solenoid mechanically triggers the cylinder valve, initiating agent discharge into the protected hazard within the response time demanded by the system’s engineered design.

As the official authorized partner and exclusive regional representative for Kidde in Oman and the GCC, Seven Star LLC proudly supplies the WK-890181-000 electric control head to data centers, industrial facilities, and marine vessels across the Sultanate. Every unit shipped from our Muscat-based inventory is genuine Kidde factory stock, fully compatible with existing Kidde CO2 and clean agent cylinder valve assemblies, and backed by regional commissioning support for fire suppression system maintenance and upgrade projects.

Operating Principle

The WK-890181-000 uses a 24 VDC solenoid actuator that, upon receiving an electrical discharge signal from the connected fire alarm or suppression release panel, drives a mechanical striker pin into the cylinder valve’s puncture disc or pilot mechanism. This releases the stored pressure of the CO2 or clean agent, opening the main cylinder valve and allowing the agent to flow through the distribution piping to the protected enclosure. Because actuation is purely electromechanical, the control head provides fast, repeatable response without depending on pneumatic pilot pressure for the initial trigger signal.

On multi-cylinder or bank-configured systems, the control head can be specified for either the primary bank or the reserve bank, with the reserve bank control head typically wired through a selector or lockout valve arrangement so that a second full agent charge remains available if the primary discharge fails to extinguish the fire or a subsequent incident occurs before the primary bank can be recharged. This layered actuation architecture is standard practice in high-value occupancies such as data centers and engine rooms where suppression system reliability is mission-critical.

Engineering Design of the Kidde WK-890181-000

The WK-890181-000 is constructed for direct mounting onto the cylinder valve outlet of compatible Kidde CO2 and clean agent cylinders, with a compact solenoid housing rated for continuous standby duty in mechanical rooms and cylinder storage areas. The unit accepts a standard 24 VDC control signal from the facility’s fire alarm control panel or dedicated suppression release panel, and its wiring terminals are designed for straightforward field connection during system commissioning or control head replacement.

Because the control head is a direct factory-specified replacement part for Kidde’s CO2 and clean agent cylinder valve platform, installation preserves the mechanical and electrical interface of the original system design, allowing maintenance teams to replace a failed or aging control head without re-engineering the release circuit or cylinder valve assembly. This makes the WK-890181-000 the correct specification when servicing legacy Kidde suppression systems where continuity of the existing releasing circuit design is required.

Key Features

The Kidde WK-890181-000 electric control head delivers reliable, fast-acting cylinder actuation for CO2 and clean agent fire suppression systems:

• Operates on a standard 24 VDC control signal from the fire alarm or release panel.
• Provides fast, repeatable electromechanical actuation independent of pneumatic pilot pressure.
• Is a genuine factory-specified spare part for Kidde CO2 and clean agent cylinder valves.
• Supports both primary and reserve bank configurations in multi-cylinder systems.
• Preserves the original releasing circuit design when used as a direct replacement part.
• Suited for continuous standby duty in mechanical rooms and cylinder storage areas.
• Simplifies field wiring with standard terminals for commissioning or replacement work.
• Maintains compatibility with existing Kidde system documentation and datasheets.

Industrial Applications

The WK-890181-000 is specified in data centers, telecommunications facilities, marine engine rooms, and industrial electrical switchgear rooms protected by Kidde CO2 or clean agent total flooding fire suppression systems. Its role as a certified cylinder actuation component makes it a standard maintenance and upgrade item for fire protection contractors servicing existing Kidde installations across critical infrastructure sites.
